Rails 4 (beta1) depends on Rdoc ~>3.4 but Ruby 2 on Rdoc 4

So this fact makes ri not work in a Ruby 2 + Rails 4 project at the moment… I suspect this could be the reason why docs were not included by default by RVM. Or possibly the other way around, due to the fact that docs are never included by default (so seldom used), Rails developers didn’t see there was a problem.
